Live System

Taking responsibility for
Live Systems during my studies

A massive project over two and a half years (01/2021 – 09/2023) where I learned what it takes to build an architecture that must perform under the pressure of real users creating big data continuously.

The focus lay on developing server-client logic in Lua and perfectly structuring data maintenance during live operation. A bug must never crash economies or inventories.

Preparing internal knowledge bases and keeping event listeners clean.

SQL Query Load

Thousands of queries hitting the database required serious SQL Optimization strategies.

🛡️
Strategy Asynchronous caching layers and carefully designed indexes prevented bottlenecks in live operation.
📦

Versioning

Strict release management and versioning through Git ensured smooth updates.

🛡️
Workflow Separation of development, staging and live branches. Documentation of updates for the moderation team.
🤝

System Support

Technical support and systematic troubleshooting (2nd-Level) of bugs reported by the active community.

🛡️
Operations An active ticket system and logging helped identify and reproduce use-case bugs.
